Microsoft Corporation said a member of its board of directors, Emma N. Walmsley, will not stand for re-election at the company’s 2026 annual shareholder meeting. The company disclosed the decision in a filing with the Securities and Exchange Commission.

According to the filing, Walmsley told Microsoft of her decision on Wednesday. She has served on the board since 2019 and will remain a director until the annual meeting.

The filing says her decision is “not as a result of any disagreement with management on any matter relating to the Company’s operations, policies, or practices.” Microsoft did not give any other reason for her decision.

The company reported the change on a Form 8-K, a document public companies file to tell investors about significant events. This one was filed under the section that covers the departure of directors and certain officers. Brian B. DeFoe, Microsoft’s corporate secretary, signed the filing on behalf of the company on Thursday.

The filing does not say when the annual meeting will be held. It also does not say whether the board plans to name a replacement for Walmsley or change the number of seats on the board. It does not describe her committee assignments or any of her roles outside Microsoft.

Microsoft is based in Redmond, Washington. Its common stock trades on the Nasdaq exchange under the symbol MSFT.
